CLOSURE FOR BOTTLES, JARS, AND OTHER RECEPTACLES.

Application filed December 24, 1919. Serial No. 347,119.

To all whom it may concern:

Be it known that I, JOHN H. MONTGOMERY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Closures for Bottles, Jars, and Other Receptacles, of which the following is a specification.

This invention relates to closures for hottles, jars and other receptacles, and particularly to the type of closures known as sprinkler tops. These sprinkler tops are generally of metal, perforated as to that portion which covers the mouth of the receptacle, and with a threaded skirt that engages with threads formed on the exterior mouth portion of the receptacle, to hold the cap in position.

Particularly in cases where the receptacle is made of glass and the cap of metal, the fit of the cap must be somewhat loose, in view of the possibility of breakage; conseuently there is likelihood of the escape of tie receptacle-contents by way of the space between the neck of the receptacle and the interior wall of the closure skirt; also of evaporation of the receptacle-contents. and dissemination of any odorous principles held by the contents. And this leakagetakes place, even though valve means he provided for closing the perforations of the cap, or a separate paper or, other cap be applied over the sifter cap.

In many instances, also, though the leakage of the contents, etc., is not of particular importance, :1 very objectionable feature is that the access of air to the interior of the receptacle, made possible by the loose fit between the cap and receptacle has a deleterious efi'ect on the contents. Furthermore, the loose fit before mentioned is objectionable per se, because the cap is apt to come off entirely, due to vibration, etc.

The closure hereinafter described aims to overcome the objections above noted, and at the same time provides a closure which is simple and economical to manufacture.

Other objects and aims of the invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as part of this specification, and in which I have. shown merely a preferred form of embodiment of the invention, Figure 1 is a view, partly in side elevation, and broken away to show the remainder in section, illustrating the mouth portion of a bottle or receptacle; Figure 2 is a top plan view of the subject-matter of Figure 1, showing the metallic or outside cap partly broken away and in section to reveal the supplementary non-metallic cap thereunder; and Figure 3 is a perspective view of the supplementary cap.

Referring to the numerals on the draw ings, there is shown at 4 a glass receptacle, with a mouth portion 5. Where a threaded cap or closure is to be used the neck portion of the receptacle below the mouth is threaded. as indicated, and a cap or closure 6, which may be of metal, has a part 7 that covers the mouth, and a depending skirt 8 threaded to correspond with the threadson the receptacle. Between cap 6 and the receptacle is a supplementary cap 9 (Fig. 3), preferably of compressible material, with a portion 10 stretched tightly over the receptacle mouth, and a skirt 11 that conforms to the threaded exterior neck of the receptacleto hold the supplementary cap firmly in position. I prefer to use for the purposes of this inside. closure a cap of suitable size and shape, made of hydrated cellulose or equivalent material, which is applied in a wet condition over the mouth of the receptacle, and upon drying contracts and so fixes itself in position as indicated in Figure 1. Thus a cap is provided which holds its position, and which substantially seals the receptacle. Such a cap is not ornamental, and in order to give a finish to the sealed receptacle, as well as for other reasons in some instances, a cap of metal such as indicated at 6, may be screwed down over the mouth of the bottle. The skirt 11 of the inside cap is compressed between the exterior of the bottle neck and the skirt 8 of the outside cap, and

so provides a packing to hold the outside cap against coming off accidentally, and also of course prevents escape of the receptacle contents by way of the space between bottle neck and outside cap, or the passage of am into the receptacle. These results are obtained without covering or concealing in any way the outside cap, which is often ornamental in character, and which protects the .cap 9.

In, some cases the outside cap is perforated, as indicated at 12, for the sifting or sprinkling of powder contained in the receptacle, the perforations being controlled by valve devices, if desired. In such instances the receptacle may remain sealed, safe against loss or deterioration, until the contents are to be used, when, by means of a pin inserted through the open perforations of the outside cap, the inside cap may be pierced (these perforations of the inside cap are indicated by dots and the numeral 14: in

Figure 2). Through the registering openings of the two caps the contents of the receptacle may be dispensed. Since the 1ns1de ca is fixed in position, and the outside cap re atively rotatable, it is evident that the registry of the perforations in theinslde and the outside caps may be readily destroyed by slight rotation of the outside cap, whereby the bottle is again substantially sealed.

An important feature of the invention is the combination of an outside cap having a screw-threaded or equivalent holding portion, cooperative with the correspondingly shaped exterior mouth portion of a receptacle, and a secondary cap of compressible material shaped to and holding itself in position over the receptacle mouth and upon the exterior mouth port-ion of the receptacle, the secondary cap sealing the receptacle, and acting as packing between the receptacle and the outside cap.

Inasmuch as many changes could be made in the above construction, and many ap parently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the langua e used in the following claims is inten ed to cover all the generic and specific features of the invention herein described and all statements of the-scope of the invention which, as a matter of language, mi ht be said to fall therebetwee-n.

1. A bottle or thelike receptacle provided cxteriorly adjacent its mouth with a holding portion, and having a closure comprising an outside skirted cap with its top covering the mouth of the receptacle, the skirted portion provided with a holding portion cooperative with the exterior holding portion of the receptacle, and a secondary skirted cap of hydrated cellulose shrunk onto the portion of the receptacle which is covered by the closure and which is compressible between and relatively to the outer cap and the covered portion of the receptacle, the top of the secondary cap sealing the mouth of the receptacle and its skirt constituting a packing between the receptacle and the skirt of the outside cap.

2. A bottle or the like receptacle provided. exteriorly adjacent its mouth with a threaded holding portion and having a closure comprising an outside skirted cap with its top perforated and covering the mouth of the receptacle, the skirted portion provided with a threaded holding portion cooperative with the exterior threaded holding portion of the receptacle, and a secondary skirted cap of hydrated cellulose shrunk onto the portion of the receptacle which is covered by the closure and compressible between and relatively to the outer cap and the covered portion of the receptacle, the top of the secondary cap sealing the mouthof the receptacle and its skirt constituting a packing between the receptacle and the skirt of the outside cap.

3. A bottle or the like receptacle provided exteriorly adjacent its mouth with a holding portion, and having a closure comprising an outside skirted cap with its top covering the mouth of the receptacle, and a secondary skirted cap of hydrated cellulose shrunk onto the portion of the receptacle which is covered by the closure and compressible between and relatively to the outer cap and the covered portion of the receptacle, the top of the secondary cap sealing the mouth of the receptacle and its skirt constituting a packing between the receptacle and the skirt of the outside cap and closely engaging the holding portion exteriorly of the bottle mouth.

4. A bottle or the like receptacle provided exteriorly adjacent its mouth with a holding portion, a skirted cap covering the mouth of the receptacle, the skirted portion of said'cap provided with a holding means cooperative with the holding portion of the receptacle, and a compressible skirted member shrunk into sealing position over the mouth of the receptacle with its skirted portion interposed between the holding portion of the receptacle and the holding means on said skirted cap.

5. A receptacle closure comprising an outer rigid cap member having a skirted portion adapted to engage the side walls of the receptacle adjacent the open end thereof, and a compressible lining covering the side walls of the receptacle adjacent the open end and forming a packing between the receptacle and the skirted portion of the rigid cap.

6. A receptacle closure comprising an outer rigid cap member having a skirted portion adapted to engage the side Walls of the receptacle adjacent the open end thereof, and a compressible lining covering the open end of the receptacle and extending down over the side W1llS Of the receptacle and 10 forming a packing between the receptacle and the rigid cap said rigid cap having perforations through the top thereof.

In testimony whereof I aflix my signature.

JOHN H. MONTGOMERY.
